Question

Find the axis of symmetry of x=2. Also find the axis of symmetry of x^2+6x-1.

Answer 1

f(x)=-2x^2+6x-1

graph( 300, 200, -6, 5, -10, 10, -2x^2 +6x -1) (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, -2x^2 +6x -1).
Vertex (1.5,3.5)
Axis x=1.5
Points (0,-1) (1,3)

Answer 2

hope that help

Answer 3

the general form of a quadratic is y = ax^2 + bx + c

the axis of symmetry of the quadratic is found using x = -b/(2a)

in your question a = 1 and b = 6

y=x^2 + 6x -1

the the axis is symmetry is x = -6/(2 x 1)

x = -3

Answer 4

the axis of symmetry of x = 2 is y = 0... or the y-axis
